I have very fond memories of playing Federation vs Zeon. This led me to pick up Zeonic Front and, eventually, Crossfire. Obviously they were very different from VS but I was already a fan of the anime so it didn't take much to sell me on it.
I can't believe that I completely missed this game! FvZ was easily one of my favorites to pick up and play, over and over again. I'm going to have to get a PS2 again just for this (my launch PS3 died and now I have slim).
Are there any other good Gundam games released in NA? I have PS3, Xbox, Xbox 360, DS, PSP (as soon as I get it back), and a laptop that isn't awful, I just don't use it much for games.
I've played/own FvZ, Zeonic Front, Crossfire, and possibly one or two more that I just can't remember. The only NA release I remember avoiding was Journey to Jaburo.
Use the GameStop website; you can search the game and find it by store. Put a hold request on the item and they'll even set it slashes for you. I got it the day I posted here and also got encounters in space, Fed vs Zeon (again), and just yesterday got SEED: Never Ending Tomorrow.
